Posted on April 01, 2017 at 20:22Hi,Trying to do a ADC continuous scan with 4 sequential channels using DMA, ending up with one single DMA Transfer Complete Interrupt, though I am clearing the TC interrupt. The single transfer has the correct ADC re...

Posted on April 02, 2017 at 08:19Hi, I am following STM32F411RE-Nucleo example for UART_HyperTerminal_IT.My first TX_IT works great. The problem is in the second call to HAL_UART_Transmit_IT() which fails on if(huart->gState == HAL_UART_STATE_READY)...
Posted on April 02, 2017 at 16:42I am fairly new to ARM and I am running into an issue with the ST Standard Peripheral Driver. If I download my project to my STM32F103 at Vector 0x08000000, it runs fine. If I use my bootloader to load my project to ...
Posted on April 02, 2017 at 20:38Hi,I am updating an old project that was built on the 'STM32 FWLib', so I am porting everything over to the new Stm32Cube HAL. The real motivation is to get the proper I2C driver in the HAL, but I am unsure how to ha...
Posted on April 03, 2017 at 10:55In function OnMacStateCheckTimerEvent there is a line:LoRaMacParams.ChannelsDatarate = MAX( LoRaMacParams.ChannelsDatarate - 1, getPhy.Param.Value );The problem is that LoRaMacParams.ChannelsDatarate is an unsigned 8...
Posted on April 03, 2017 at 05:07I've been playing with the hal sd card driver today.printf(' Product name : %lx%x\r\n', pSD_CID_Info.ProdName1, pSD_CID_Info.ProdName2);where pSD_CID_Info is of the type HAL_SD_CardCIDTypeDef which istypedef struct{ ...
Posted on March 31, 2017 at 23:59I am using ADC1 in scan mode. When I run my code normally through the debugger, it works just fine. However, when I remove the debugger and directly run it, I am seeing extremely low voltages. What could possibly be ...
Posted on February 08, 2016 at 10:01Hi,i have connected a external clock on stm32f4 microcontroller but the hse is failled to startup the application code (the internal clock works perfectly though.)
