Resolved! Using of LPUART1 on L031K6
I'm trying to receive data from the LPUART1 serial port on the L031K6 development board.Unfortunately all my aproaches failed so far.Sending data works fine in all three modes:BlockingNon-Blocking ITNon-Blocking DMAI'm routing the LPUART1 to PA2 and ...
something like TI debug waveform?
Hi!How does ST ecosystem helps MCU debugging? TI has their debug waveform which seems being liked by many engineers.
[STM32G0] Analog watchdog interrupt always activated even when the voltage in the guarded window
Hello,I am experiencing the AWD interrupt always being activated when using the analog watchdog on the STM32G0B0 to guard channel 0. Here is my configuration:systemclock = 64MHz ADC ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4 Resolution = 12B Con...
Interrupts in EEPROM emulation(AN3969)
I'm trying to implement "AN3969 EEPROM emulation in STM32F40x/STM32F41x microcontrollers" on STM32F407.According to the documentation, "Interrupt servicing during program/erase is possible".However, when actually installed, interrupts stop completely...
SPI without CS
I am using TLC5941 Led driver and it communicates with Nucleo-U575ZI-Q and SPI on TLC using three wires only clock, MOSI and MISO and there is no CSso I have an issue with connection so my question is:Is there a way to make SPI on stm32 without CS?
Resolved! STM32C0 MCU brings 32-bit kick to 8-/16-bit cost-sensitive applications
The new STM32C0 series comes to complete the STM32 Mainstream MCUs portfolio.The STM32C0 series is the most cost-effective STM32 MCU. It bridges the gap between 8- or 16-bit MCUs and higher performance 32-bit MCUs. Built on the same technological pla...
Nucleo F401R1 - Timer interrupt and lockup
I am using timer interrupts to read 2 optical encoders connected to 2 motors. Everything seems to run fine for a while, then I get a hard lockup and everything stops. The time can be 5 minutes or 2.5 hours. I installed and setup watchdog and when it...
For STM32L4S5, how to access the calibration register and how to calculate what values to store in that register? We're having a problem with the calibration of the real-time clock. It's significantly off-time over a period of several days.
We believe there is a register setting to calibrate it, how can we debug this issue please? What are the steps to calculate the calibration register value and how do we get them into the register?
