Hi all,I'm having some trouble getting DMA to service sequential uses of I2C+DMA transactions.I can have the I2C+DMA initialize our demodulator, which involves some 12,000 reads and writes. (So, I2C+DMA works *very, very well* when it works.) I ca...
Posted on March 29, 2018 at 04:32I am trying to get the STM407VET to communicate to an SD Card using the SDIO interface and drivers. Code base was generated from CubeMX and Eclipse is the IDE. Debugging with Open OCD. Hardware is custom. I have trac...
Hello,I have a little confusion regarding FMC memory map. I hope someone can help me with it.Accoring to reference (stm32h743) FMC external memories are mapped as following:0x6C000000 -0x6FFFFFFF FMC NOR/PSRAM/SRAM 4 Bank1 (or remap of FMC SDRAM Ban...
Hi,I am running into a strange problem, I am using strncpy function to copy one array into another. If i include this in my code i get a Hard fault DEBUG_VT . I have read quite few article on hard faults and how to track them down but this one that i...
So I've just bought a F722ZE based board which is ideal for the projects I'll be working on, however I was hoping I could get this to work with the arduino IDE and save myself the trouble of learning the new platform, but this doesn't seem to be poss...
Thank you in advance.I am trying use two stm32f103c8t6 to do communication stuff. One is used to be transmitter and another is receiver. The code is simple but it doesn't work. Source code as follows:Transmitter:while (1) { uint8_t tran...
Hi everyone!I’m working with a STM32L475RE design. The project works completely fine in “debug mode�? (using ULINK2) but doesn’t work in release mode. I’m trying to find the code part that could be the problem, using a LED on the initiation. However,...
Thank you for the new I2C peripheral in STM32H7, this really looks VERY much improved compared to STM32F4.Can the STM32H7 I2C in master mode somehow "free the bus" in case of "stupid slaves holding the SDA line down"?It is a quite common problem of I...
Posted on June 28, 2018 at 13:29Hi all,I'm trying low power modes of the STM32. I've noticed that HAL_PWREx_EnterSTOP2Mode synopsis mention that: * The voltage regulator is set in low-power mode but LPR bit must be cleared to enter stop 2 mo...
