Hi all.I'm currently writing my own set of drivers based on the provided stm32f7 header written by ST. I'm a little confused understanding the USB reset values in section 37.15 of the reference manual. The reset values for my GPIO, APB, and a few oth...
Hi there,I have configured ST32F207VGT for FSMC asynchronous muxed NOR configuration, FPGA is connected to the bus at other end. Following is the FSMC configuration done on MCU hnor1.Instance = FSMC_NORSRAM_DEVICE; hnor1.Extended = FSMC_NORSRAM_E...
Posted on April 05, 2018 at 10:56We are trying to increase the clock speed of our STM32 on our custom board but we encountered some difficulties.At the moment, we set a clock of 56 MHz, using HSI and an PLL of 112 (with CubeMx). It works fine.But wh...
RM0433 is very short about the SYSCFG_UR registers. Most URx registers are read-only and probably provides another view at the values of the options byte. The reason to provide another view is not clear to me. However UR2 (BOOT_ADDR0) and UR3 (BOOT_...
For a 21-channel temperature measurement tool (NTCs) I use a STM32F373 ( SDADC1 + SDADC2 + SDADC3). I replaced a temperature sensor with a fixed resistor for these tests.The behavior of the ADCs is different and reproducible after startup:Good Case: ...
Is there a known problem with HAL ADC driver in the 1.12.0 L4 HAL library?I have working code using STM32L4 HAL 1.8.1 that I recently upgraded to latest Cube & HAL (4.26.1 & 1.12.0 respectively) and I have very odd behavior with the ADC after the upd...
Hello, I have a STM32f429i-Disc1 board and trying to run a simple usb-cdc code. I've watched many videos on youtube and looked over many examples but I couldn't make it work. board won't appear as virtual com port on device tree. I downloaded stsw-st...
Posted on July 02, 2018 at 12:49Hi Friends !As discussed in my earlier post we have developed 44 Keys capacitive touch key pad with 4 layer PCB board in Matrix touch scheme between two touch TSC groups with Layer 1= top Digital track, Layer 2= shiel...
While implementing a course temperature monitor for our custom boards I noticed, that the readout of the two calibration values shows TS_CAL1 greater than TS_CAL2:According to documents "https://www.st.com/resource/en/reference_manual/dm00031936.pdf"...
