Posted on December 10, 2013 at 19:21I have a board of my own design using the STM32F427 and several 407 demo boards (Olimex H407 and Disco4). I am pretty sure that my design is working correctly. I am also pretty sure that the dfuse tester and demo...
Posted on March 08, 2017 at 15:51Hi I have a custom bootloader that I flash to the first sector (0x8000000) and when it receives a new program it loads it to 0x8003000. I can jumps to the user application,and also jumps from user application to the...
Posted on March 09, 2017 at 08:11Good DayI am using the built-in comparator on a STM32F072RB. The comparator works fine, but now I want to be able to measure the amplitude of the sine-wave (already withing 0-3.3V limits) by 'removing' the pin from t...
Posted on March 07, 2017 at 14:32Hello,I'm working with the STM32L475 micro. In my application I read several analog values using the ADC1. Values read are quite similar when device is in run mode. But, according to my specs and in order to save pow...
Posted on March 08, 2017 at 14:25I'm using HAL_CAN_transmit to send data for stm32L4 mcu. I'm trying to send frames with 2 bytes in an infinite loop.I would like to know if it's possible and if feasible to measure TTL signal levels at GPIO TX pin of...
Posted on March 08, 2017 at 02:48Hi everyone,I'm trying to complete a project with the STM32F4 Discovery board and with a PHY IC (DP83848CVV), along with FreeRTOS and LwIP. I began the project with first testing the hardware this previously complete...
Posted on March 07, 2017 at 17:54I am working on a board (STM32F407VGTx) that has an older PHY chip KSZ8721BL. I have similar code running on the MCBSTM32F400 (v1.2) which has an KSZ8081RNA. In testing, I retrieved all of the registers from both PHY...
Posted on March 05, 2017 at 07:29Hello everybody,How can I use DMA for this HAL_SD_WriteBlocks,I tried with HAL_SD_WriteBlocks_DMA, it doesn't work,Any clues ?Thanks======================int8_t STORAGE_Write_FS (uint8_t lun, uint8_t *buf, uint32_t...
Posted on March 05, 2017 at 12:01In simply words:I want to transfer data from PC via USB to STM32.I want to (somehow?) recognize data - some data should be saved to uint8_t Data1[20], and other data to uint8_t Data2[20].My question is:- should I cre...
