Posted on November 17, 2017 at 03:33HI. Please help.CPU : STM32F207Use the tcp_echoserver example to send and receive data. #define TCP_MSS 1460, #define TCP_TMR_INTERVAL 250If data is sent in tcp_echoserver_poll function and the data to send at ...
Posted on November 17, 2017 at 01:27I generated the code for a STM32L496 that hopes to use the SDIO with an external SD card. To meet my data throughput, I will need the 4 bit bus and the high speed mode which the L496 appears to have. However, the ...
Posted on November 16, 2017 at 20:16Hello,I have made my custom boards inspired from nucleo board l073 but i cannot reach the same power specifications as the nucleo board. Indeed, with the same firmware, on the nucleo board, i consume 3uA whereas o...
Posted on November 16, 2017 at 16:54Dear community,my setup is build on top of stm32f439 and ADS131e4 ADC connected through spi.The adc is set in continuous mode, so it fires an impulse on a pin (DRDY) as soon as a new sample is ready.The sample con...
Posted on November 15, 2017 at 19:54I am using STM32F042F6 uC. I am not sure why this HAL_PWR_EnterSTANDBYMode() does not put the uC to sleep mode. But the odd thing is in certain condition, it does go the Standby mode, but in some other boards, t...
Posted on November 15, 2017 at 17:13 Hey. I have a board with the smallest STM32F100, with 4K RAM and 16K flash. It has only DMA1. I am using CH3 for circular DAC output already. So, for the only SPI(1) on that MCU, the DMA map in the refm...
