We are building a Bluetooth analog sensor module using the STM32 and decided to migrate from the F-series to the G-series to take advantage of the reduced power consumption. However, things that were easily working on the F-series are not on the G-se...
Hi,I just read an article mentioned that micro controller will limit (or do smthing) to lower down the frequency of crystal oscillator to match the multiply number of 9600 for UART, is that right?So if I'm using PLL to boost CPU frequency from 8M t...
Hi all,I have problem to get work stm32h743 as parallel synchronous transmission with DMA and 16bits GPIO and timer as clok. I need something like in Application note AN4666 but for H7xx.I'm using GPIO port E what is on AHB4 and it si D3 domain and...
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...
