The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi,I'm using a STM32G030 controller and I'm working with ADC Timer-triggered and DMA for storing the data. I need a quad-buffered DMA that generates an interrupt when 1/4 of the buffer has been filled. I'm not experienced with this so I'm asking some...
Hello, I'm trying to debug an custom board with STM32L010C6 and STLINK V2. The firmware download seems to work fine, but the debugging is not working. The execution stops here:0x1FF00220 4800 LDR r0,[pc,#0] ; @0x1FF00224I've already tried to brea...
Purpose: try to print "hello world" .Status: VCP shown in Device Manager as COM3. Putty can connect. Nothing displayed, tried other serial port debug tool. No success. simple code, except HAL_UART_Transmit, all others are auto-generated by CubeIDE. U...
I have a problem that the PWM timer stops working randomly, maybe once every 2 weeks on 4 prototoypes. The PWM signal is just high instead of the frequency it should do. I have added reset and recover but nothing seems to fix. Since I am not able to ...
I am using the STM32F407VET6 and SPL libraries. My goal is very straightforward, just send data over usart periodically.But when I send data (buttoncheck function) inside the timer interrupt it stucks " while(USART_GetFlagStatus(USART3, USART_FLAG_TC...
I need to write to the 4kB battery backed SRAM to hold information across power cycles, but it's not working! To be more specific:The debugger memory display shows the correct data in SRAM after a write.The data is read successfully at any time other...
HelloIm trying to implement stm32 spi multi-master function on a stm32f765 according to the below presentationI keep getting MODF error when transmitting as a master, that would indicate that the slave sets the masters NSS pin low. Even if I set the ...
HiI'm doing a project to detect collision on UART, when I get data from Rx, I will compare it with the data I transmitted, if there aren't the same, means collision occurred, then I will immediately stop my transmitting interrupt to stop sources wast...
Hi there, I'm using an STM32F103C8 and using the SPI1 interface with software CS together with DMA1 Ch2 and 3 (RX and TX, respectively) in master mode. Here is how I init my transactions:DMA_ClearFlag(DMA1_FLAG_TC3 | DMA1_FLAG_TE3 | DMA1_FLAG_HT3 | D...
