Description of the system-memory-stored manufacturing-time-acquired constants for temperature sensor (TS_CALx) and VREFINT voltage (VREFIN_CAL) are given for certain VDDA voltage.However, what's important here is not VDDA voltrage but the VREF+ volt...
Heyho,got my custom board running, only (minor) problem until now:internal analog temperature sensor (ADC3) value seems to be off, showing something like ~60°C,while an external sensor shows about 30°C."Finger test" confirms rather the 30°C.I have th...
Hi,I have not developed graphic applications before and am trying to figure out how do I select an STM32 micro for a touch-display application using TouchGFX (if relevant to the question).The display I am looking at has an SDI interface and this is t...
Hello, I am slowly going crazy! I get Zero and only on Channel0! other channels are OK. Can somebody help me?
Hi guys I am a beginner of STM32 user. Now I am learning PWM. I wanted to make use of a single Timer and use 2 or 3 of its channels to output PWMs of different frequencies. I saw AN2581 app notes but unfortunately there were no sample codes there. W...
Hi. I'm not a English speaker. Sorry for my poor English.My code including EITHER I2C or SPI works successfully on STM32F303K8T6 Nucleo Board. However, with my code including BOTH I2C and SPI , Only SPI functions work correctly ,but I2Cs don't.Usin...
I want to receive the MessageRx_CAN [8] in my RxFifo 0 buffer but i cannot get that. Could you please help me out how can i implement that to get if want this requirment. DLC = 8; StdId = 0x245; IDE = CAN_ID_STD; RTR = CAN_RTR_DATA; I have attachte...
I am trying to flash the memory of the STM32-L43KC (Nucleo-32) MCU with the UART Bootloader. I have connected the TX and RX pins of the board to FTDI USB-RS232 connecter. To boot from the system memory, I have also configured the option bytes accordi...
The reference manual documentation for the onboard temperature sensor for STM32H745, RM0399, chapter 26.4.33 gives a formula for calculating temperature that is only valid when VREF is 3.3 volts, but lacks mention, foot note, etc of any kind that VRE...
I am using NUCLEO-G071RB. I use 2 ADC channels: GPIO analog and internal temperature sensor. I connect the +3.3V to the GPIO analog pin via. potentiometer. The internal temperature looks like it works well (the temperature rises slightly when I put a...
