Posted on March 24, 2017 at 11:03Hello there,Currently I'm using a STM32F407VG discovery board to testing the stm32 low power features. STM32CubeMX was used to generate a simple demo. However, it seems always not able to enter sleep mode (standby mo...
I'm on STM32F103CBT6.I have a TI DAC8564 on SPI2. It has a 24-bit input register, requiring me to TX a pair of 16-bit values (extra 8 low bits are ignored) while SYNC is low. After sending, I have to toggle SYNC high and then low to begin a new wri...
I don’t understand the behavior of the _C ports. According to the datasheet, the pin type for PA0_C is listed as ANA (analog input only). However, I can configure it as an output and successfully generate a square wave by toggling it in a loop.Given ...
Hello,STM32F103RB microcontroller.I want to use Using one timer as prescaler for another timer mode (see figures below).I want the slave timer to increment its counter every time the master timer generates update events. But the slave timer does this...
Hello,I wanna read an external ADC.The ADC has following serial process conditions:1. Get a CNV signal by µC2. Convert and send BUSY=HIGH to µC3. After Convert send BUSY=LOW to µC4. µC send SCK to ADC, then ADC send data and is running as long as it ...
Hi! I have custom board with new mcu stm32l562ve. Board has out pins - SWDIO and SWCLK.I am try connect by st-link v3. But mcu not connected. Also, i tested with connect nRST ( setting "Under Reset" in st-link ). But this variant same as first. MCVU ...
Hi I am wanting to use the LPTIM to break out of STOP2. I have a function to set the timer, and go into stop mode. After setting LPTIM1->ARR, LPTIM_ISR_ARROK in the LPTIM1->ISR is never set. After X amount of seconds, the STOP2 exits as expected,...
Hi, I have a custom board in which VREF+ is supposed to be 3.3V. But the actual VREF+ (pin32) is 2.xV, with drifts between power ups. VDDA (pin 33) is 3.3V.What's wrong with the circuit schematic? Can I just remove the resistor (R22) between VREF+ an...
When I use sleep mode while debug it sleep mode Works. But when I try runing code without using debug method it dosnot go in Sleep mode. When I chack current.When using debug method stape by stape. Without using stape by stape debug method.Hear is t...
Respected sir/madam,We are using STM32F411CEU6 blackpill board. When we try to put our code into the flash, it says it the memory is protected. Can you suggest possible solution to solve the issue?
