eg, in stm32l0xx_ll_utils.c /** * @brief This function configures the Cortex-M SysTick source of the time base. * HCLKFrequency HCLK frequency in Hz (can be calculated thanks to RCC helper macro) * @note When a RTOS is used, it is recomme...
Anyone have an example of a TCP/IP echo server with the h563?
Hello,I have a STM32 sending a packet a second, up to 25 UDP packets, to another STM32 whose role is to echo these packets back to the sending STM32.Inside the packets is a value which I increment after every transmission.I've noticed that at the ori...
Hi everyone, I am trying to write modbus tcp/ip server(slave) with stm32h7. I know the Modbus working logic and I have worked with Modbus RTU many times before, but I am unfamiliar with the ethernet layer. I couldn't find a resource to write modbus t...
I've been having this problem where I configure my STM32F303VCT6 to send out 8 bits but the CLK sends out 16 cycles. I already tried casting the data as proposed on other forum posts but it doesn't work for me. Does anyone see the problem? - - - Libr...
I've been doing a lot of embedded coding lately. I'm not a very experienced developer and I have been trying to develop a set of design guidelines to help me up the learning curve. I'd appreciate hearing what experienced embedded developers use for ...
I am using a nucleo-f767zi to control a reverdi tft display.The project in CUBEMX ide is using freertos and there for the time base is changed from systick to TIM6.I am trying to task enable sequence for the screen but i see that i am stack in an inf...
I upgraded my project to the latest IDE and TouchGFX. I opened the IOC file to change a setting and now the project doesnt compile with the following errors. Before opening the IOC and generating new code, the project compiled just fine. Here is wha...
