Has anyone got working example code they could share of setting up DMA to transfer from memory to a GPIO port on an H7 (Nucleo-H743). I've read AN4666 and can get the example working on a L476 but none of the many variants I try on the H7 work. The...
Hello I am using the STM32F411E-Discovery board, selecting the HSE ceramic resonator, which is installed on the board as 8.000 Mhz Crystal, as clock source for a 1 sec interrupt with TIM2. I am using STM32CubeMx BUT INSTEAD OF HAVING 1 SECOND INTERRU...
Hi there !I use uart with DMA for receive data from (right now) pc and STM32F051 discovery board, everythingh work bettere if i send all data, but if i send less data stop the work . Let me explain i need the send 180 bytes from pc to discovery boa...
We have two same design Board, one is fabricated in last year, another one is this year fabricated boards and i loaded same code for both boards.Achivally this year what i fabricated with little changes on the Connector side and we are used buffer ic...
Hello, I am using the example code BLE_Throughput from the BlueNRG-2 DK to program a PCB. The example is working fine but the frequency of advertisements is too high for what I need and I could not find in the code where can I change it. Could someon...
Hi.I have a program that sometimes fails to send data on CAN but still receives them correctly.This is on an STM32L462 using 1.4.2 IDE and latest API.For some unknown reasons, at one moment, out mailboxes never empty. It can be anytime from right upo...
I'm working in a project that involve a thermal camera image processing.I need to process a buffer of 384*288 (16bits) in fastest way possible.I'm using the 480Mhz VCO template to set the procesor in 400Mhz (Cache enabled).I already did some code op...
HelloWhen debugging, I obviously use ST-Link and Keil displays register values for meCan I export these values somehow without having to transmit them over UART?I need these values for later graphing in python and UART would just take unnecessary scr...
Hello,I am encountering an issue with the STM32F413 MCU: when transmitting data over UART, there is a short delay between the stop bit of one byte and the start bit of the next byte when transmitting data one byte at a time. I compared the behavior o...
