Hello,I need to implement an i2c passthrough between i2c ports i2c1 and i2c2 on my stm32g031k8 board. This MCU is connected to another CPU board using i2c2 port. Also, the i2c1 is connected to a temperature sensor, RTC, and EEPROM. After power UP, u...
The original (Rev 1) datasheet said that STM32F030x4, x6, and x8 all had the Periodic Wakeup:The current (Rev 5) datasheet, which adds the xC variant, now says that only the xC has the Periodic Wakeup:So what happened?How/why did it disappear from th...
Hi!At what speed would code in external flash memory execute? At the clock freq of the external flash or the by main clock freq of the MCU, or by some combination of the two?I assume once the code is fetched from the external flash, it would execute ...
Hi,I am doing the MTBF calculation of our product which contains STM32F205RCT7. Can you provide me with the MTBF value of STM32F205RCT7?Thanks in advance
Hi, I have an issue when trying to copy a struct by direct assignment on STM32H743; The code: void function(const structName_t *incomingStruct) { Signal_t sendSignal; sendSignal.desiredStruct = *incomingStruct; // <-- Causes unaligned access .....
The example project does not provide information on ADC4 register configurations, ADC4 seems to be different then prior peripherals (e.g. compared to L4). ...\NUCLEO-U575ZI-Q\Examples_LL\ADC\ADC_SingleConversion_TriggerSW_IT_InitSTM32CubeMX configur...
I am having weird issue with STM32F767 (configured to run at 200mhz) that needs to be SPI slave .. I configured it with 0,1 (clock low, second edge), hardware cs.. when master sends data at 350kbps everything is ok, when master sends at higher speeds...
I am using STM32H735,TFBGA-100 controller with 550MHz.I don't need ADC and DAC functions.1.Shall i connect VDDA,VREF+ and VssA to ground(Vss)? if yes, what is the recommended(through any resistor or shorted)way to connect to Vss?2.If i did as above,...
It is really frustrating to not find an information, even worse, you always have to login again with writing your full emailadress, while you checked "save login" before! Here is what i am looking for (this is all i found as register for privilege mo...
In stm32f429t6, the uart8 dma rx function works on 3 out of 5 boards and does not work on 2. The same firmware was applied to 5 boards, and if only the uart8 interrupt was used without using dma, the 5 boards mode operated normally. What is the cause...
