Hi,In my project two 16 bit timers chained together to achieve 32bit capture resolution. TIM3 as master timer and TIM4 as slave timer clocked by TIM3 overflow event (TIM4 works in external clock mode 1). Capture signal is connected to both timers inp...
Hello, I am trying to make communicate a NUCLEO STM3F030 with a STM32F030K6T6 mounted on a custom pcb.Tx sends from NUCLEO is ok when i check it on an oscilloscope but when i connect the power supply of my pcb on the NUCLEO (or even on an external p...
Hello,I have a STM32F769I-EVAL board, where the Firm.Ver is V1.2.0In the package I download, I only have the 1.0.0 Hex version file.Before doing any test and erase the current version, to be able to load back the 1.2 version, I would like to downloa...
I am using an STM32F429VGT6 with SWD debugger, and OpenOCD software 0.10.0.I am trying to dump the contents of the flash memory at 0x08000000 through debugger.If I don't use any WFE/WFI in my code, this works fine.If I put a WFE at the beginning of t...
I am having issues interfacing with the B-L475E-IOT01A's on-board SPBTLE-RF bluetooth chip. I am able to send header packets inquiring about the the bluetooth chip's write and read buffers. I have confirmed that I am doing this correctly, because I g...
Hello all,I'm trying to prototype a shutdown mode with a RTC alarm.I'm flashing the LED 5 times, then I set-up the RTC calendar, clock and alarm A (5 seconds after set-up clock). Then I go to shutdown mode. Everything works when I program my system (...
Hi, I've been trying to compile a program to talk to a sensor over UART for my STM32L476RG board. I'm having an issue with that I've tidied up the library that is needed to talk to the sensor, but I'm getting errors that I'm missing header files such...
In an attempt to reduce power for a critical battery powered system, I tried, without success, to make the chip run in the power range 3 (1.2V). Here is what I do: At power up, with the chip running from the MSI clock divided by 2 (1Mhz), whatev...
I'm currently using the STM32L4R9I-EVAL board and trying to prototype an application where the microcontroller will need to be in lowest power (i.e. SHUTDOWN) mode for several days or weeks and then wake up to perform an action. I can get the the mi...
