Hi All,My application sends and receive data very frequently, Some times Tx and Rx may be occur same time, Application run for some time (10 sec or 20 sec) but after some time Rx interrupts stop working and i found ORE bit high.So My question isWhat...
We were experiencing strange crashes originating from HAL_SPI_TransmitReceive and HAL_SPI_Receive when operating in SPI Slave mode.Issue is that STM32 HAL code is not handling cases for 8 bit SPI Transfers correctly causing overflow of user buffers a...
I'm trying to follow the reference manual to use USART over USB via VCP (bare metal), but Realterm isn't able to read *any* data. According to the user manual, USART/VCP over USB should be supported, mentioning it's on the PC4,PC5 pins. Here's the co...
Hello everybody,My name is Rego, as a hobby I work on displays, image processing, etc...I'm not very familiar with ST, but I'm really enjoying these MCU. I've already implemented RTC using VBAT and it works very well. Now I want SRAM backup,On batter...
I have a small problem if I use SAI DMA in circular mode, the first time it fills up the buffer, it works fine, but after it looks like it is the right data levels, but just that some are omitted.the top chart is DMA filling up the buffer, (first run...
Hello I'm trying to communicate two L432KC between them by CAN Bus, but I can't because it seems that the mailboxes are full and the HAL_CAN_ERROR_PARAM stops the program. How can I fix it?Thank you very much
So firstly, I'll explain what I'm trying to achieve. My company is planning to utilize an STM32H7B0 because it's the chip that we were able to find stock of. For testing, I'm using a STM32H7A3 because it was available as a Nucleo board. The primary r...
A year ago I heard from a friend that there was a problem with the STM32F103's hardware I2C. All the ones I found on the internet said there was no problem with the hardware I2C of the ST, but not the F103 series. So, I have two questions. First, I w...
breakpoint reached normal;from here this jumps to "show.."and then this breakpoint seems never reached, but when going step by stepline 1354 is reached and also the following "sprintf.." , but it gets curious:when "Radio.." text is selected , is draw...
On a stm32 mcu, using HAL_I2S_Receive_DMA the clock generation is started. At first, the application went into a hard fault and nothing is subsequently written in the data receive buffer.HardFault_Handler:08000942: push {r7}08000944: add r7, sp,...
