STM32F746G-DISCO is a $49 Cortex-M7 Board with a 4.3″ LCD Display, Arduino Headers

We’ve already seen Atmel started shipping its SAM V71 Xplained Board based on its latest Cortex M7 a few days ago, but Atmel is not the company which recently introduced a Cortex M7 development kit, as ST Micro also launched an STM32F7 Cortex M7 development kit with Arduino headers and 4.3″ LCD at the end of June. The “Discovery Kit with STM32F746NG MCU” (STM32F746G-DISCO) comes with the following specifications: MCU – STMicro STM32F746NGH6 Cortex M7 MCU with 1 MB Flash, 340 KB RAM, in BGA216 package Memory – 128-Mbit (16 MB) SDRAM (64 Mbits accessible) Storage – 16 MB Quad-SPI Flash memory, and micro SD slot Display – 4.3″ 480×272 color LCD-TFT with capacitive touch screen Camera – Camera connector Connectivity – Ethernet connector compliant with IEEE-802.3-2002 USB USB OTG HS with Micro-AB connectors, USB OTG FS with Micro-AB connectors USB functions: virtual COM port, mass storage, debug port Audio […]

STMicro Introduces $5 CLOUD-ST25TA NFC Evaluation Board

STMicro has just announced a new low cost NFC evaluation board called CLOUD-ST25TA used to evaluate their ST25TA02K NFC Forum Type 4 tag chip part of their ST25TA series, previously known as SRTAG. CLOUD-ST25TA board specifications: SoC – ST25TA02K-P NFC/RFID Tag in UFDFPN5 ECOPACK 2 package Contactless interface NFC Forum Type 4 Tag ISO/IEC 14443 Type A 106 kbps data rate Internal 50 pF tuning capacitance allowing small inductive antenna design Memory 256 Byte (2 Kbit) EEPROM with NDEF data support 200 years data retention 1 million erase-write cycles endurance 128 bit password data protection 20 bit event counter for read or write access with anti-tearing feature Digital pad Configurable general purpose output (GPO) indicating, for example, RF field detection The board features look somewhat similar to NFC tags sold for 50 cents online, but it does come with more memory (256 bytes vs 144 bytes), has a longer claimed […]

How to Program STMicro STM8S $1 Board in Linux

In January, I discovered there was such thing as a one dollar development board based on STMicro STM8S103F3P6 8-bit MCU with 1KB SRAM, 8KB flash, and 640 bytes EEPROM, some GPIOs as well as I2C, UART, SPI, ADC, and PWM signals. Links to documentation and source code were provided, but development tools were only Windows based. However, one of my reader informed me SDCC (Small Devices C Compiler) supported STM8, and development in Linux should be feasible. So I decided to buy the board on eBay for $1.62, as well as an ST_link V2 programmer for STM8 / STM32 for $4.52 in order to flash the firmware. The board came pretty quickly, i.e. within 2 to 3 weeks. But due to a lost package, the programmer took nearly 3 months to reach me, as the seller had to re-send after I failed to receive it within 2 months. It comes […]

Meet STMicro STM8S Based One Dollar Development Board

ESP8266 modules are $3 Wi-Fi boards targeting IoT applications that can be used in standalone mode, or connected to another MCU based board. But what if you don’t actually need Wi-Fi, but instead require a tiny board to control a few GPIOs? Arduino Pro mini can be used for this, but it costs about $10 on Sparkfun, and it’s certainly cheap enough for most projects. Switching to Aliexpress, you can get Arduino Pro mini clones for about $2, and a bit less in 10 pieces quantities. But you can get even cheaper and add a micro USB port with STMicro STM8S based boards that can be found for 5.5 CNY (Less than $1) on Taobao.com, or – once oversea shipping is factored in – about $1.60 to $1.70 on BuyInCoins, or Aliexpress without headers, and the version with headers sells for about $2 or more. Let’s check the board specifications: […]

STMicro STM32F4 (Cortex M4) vs STM32F7 (Cortex M7) Graphics Demo

STMicro announced their latest STM32F7 micro-controller family based on ARM Cortex M7 last week. As ARM Techcon 2014 is now taking place, the company has uploaded an infomercial on their YouTube account, where STMicro and ARM representatives are interviewed about the new family, and talk about its performance, power consumption, target applications, business prospects, and so on. But there’s also an a short demo with two development kits one with a STM32F4 cortex M4 micro-controller, and the other with a STM32F7 micro-controllers. Since both MCU families are pin-to-pin compatible, the hardware is identical except for the MCU. Both kits are pre-loaded with a 3D graphics demo (ray tracer), and the board with STM32F7 completes the demo in about half the time of the one with STM32F439, allegedly with about the same power consumption (7 coremarks / mW). The video is about 8 minutes long, and the demo starts at 1:25. […]

STMicro STM32F7 Series is the First ARM Cortex-M7 MCU Family

Right after ARM’s Cortex-M7 announcement, STMicro has listed STM32F7 MCU family based on the latest ARM core on their website. The family is comprised of 20 different MCUs with various flash size, packages, and with or without a crypto/hash coprocessor. The company expects their STM32F756xx microcontrollers to be used for motor drive and application control, medical equipment, industrial applications such as PLC, inverters, and circuit breakers, printers & scanners, alarm systems, video intercom, HVAC, home audio appliances, mobile applications, Internet of Things application, and wearable devices such as smartwatches. STM32F7 MCUs share the following key features: Cortex-M7 core @ 200 Mhz (1000 CoreMark/428 DMIPS) with L1 cache (4KB I-cache, 4KB d-cache) 320KBytes of SRAM with scattered architecture: 240 Kbytes of universal data memory a 16 Kbytes partition for sharing data over the bus matrix 64 Kbytes of Tightly-Coupled Data Memory (DTCM) for time critical data handling (stack, heap…) 16 Kbytes […]

Linaro 14.06 Release with Linux Kernel 3.15 and Android 4.4.3

Linaro 14.06 has been released last week with Linux Kernel 3.15 (baseline), Linux Kernel 3.10.44 (LSK), and Android has been updated to 4.4.3. One interesting development this month is that Android for ARMv8 (64-bit ARM) is booting on the fast models using ARM Trusted firmware and U-Boot. SELinux has been enabled in Android. I could not see much new member hardware, except possibly B2120 (HDK) reference board for STMicro STiH407 “Monaco” STB SoC. Here are the highlights of this release: Linux Linaro 3.15-2014.06 GATOR version 5.18 (same version as in 2014.04) updated basic Capri board support from Broadcom LT cortex-strings-arm64 topic (same as in 2014.02) updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT. updated Versatile Express patches from ARM LT more HiP0x Cortex A15 family updates from HiSilicon LT (hip04_eth, hip04_defconfig) updated LLVM topic Big endian support (same as in 2014.05) ftrace_audit topic from […]
