Posted on July 26, 2017 at 13:32Hello,I noticed that the stm32F429 disco does not have the CS43L22 circuit nor a 3.5mm jack for audio output as its rival the F407, but it has two internal DAC output, which can be used to play a wav file.If anyone ha...
Posted on July 28, 2017 at 04:06Hi all, I've been working successfully with SW4STM32 for a few weeks now and I'm quite happy with it. Generating projects with CubeMX32 and programming and debugging works pretty well.I've been trying to compile the L...
Posted on July 27, 2017 at 05:18I'm updating an old PCB design that used the STM32L432KB. The new design is using the STM32L452CE which has the Vbat pin.In the old design I used a voltage divider across the battery and connected it to an ADC pin to ...
Posted on July 28, 2017 at 05:31Hi I'm working on STM32L476RG board when I'm using SPI Peripheral as Receive only mode .In this when im receiving 4 channels data SPI is generating 5 times clock instead of generating 4 times clock.What is the reason ...
Posted on July 27, 2017 at 17:00Using the HAL Library release 1.8.1 for the x476, I am facing problem using SD card from different company.I am successfully using an 8Gbyte Verbatim micor-SDHC memory since a year. Nowadays I am trying to use instead...
Posted on May 02, 2017 at 09:16Hi,I use the HAL Library for a STM32L4 MCU clocked at 80MHz. The time between two Bytes are 3us. This is to slow for my Application, but I can not transfer more bytes or use a DMA, because I must react on a Signal from...
Posted on July 25, 2017 at 16:25I use chip STM32L073RzTx and STM32F103C8 , compiler and IDE True Studio, HAL base coding, develop board stm32nucleo I want using printf() in UART Communication I used TDR register UART Communication good working but ...
Posted on July 27, 2017 at 22:43Hi! I'm new to using ST products, but at my internship this summer, I am using the EVAL6470H boards connected to an STEVAL-PCC009V2. I just recently got a MacBook Pro, and I was curious, has anyone tried using this bo...
Posted on July 27, 2017 at 11:55Hey guys,I have a function that parses messages of my own format and splits them into an opcode and (0-3) operands.With 0 or 1 operand, it works fine; on the second operand, the msg.substr(start, (pos - start)); cause...
Posted on July 27, 2017 at 13:23Hi,I communicate with ADS1299(24bit, 8CH ADC chip) by SPI.ADS1299 SPI specification isCPOL=0 CPHA= 1Max SCLK = 20MHzand command flow is1) send read command(0x12)2) send dummy(x00) to make SCLK and receive 27 byte data...
