I am trying to use DAC Channel 1 on STM32H7 with DMA to control the ramp-up of a PA. The DAC must always be driven (enabled). A ramp-up sequence is written at the start of a burst and a ramp-down at the end of the burst.The FIFO error flag is set on ...
Hi all,Thanks in advance for your time, appreciate it!!My doubt is over the microcontroller STM32H743ZI. It has 3 ADC modules integrated. As far as I understand, each module has a Sample and Hold, thus ADCs 1 and 2 can be coupled in order to work in ...
The information for System Handler Priority Registers if false according to ARMv6-M Architecture Reference Manual issue C
Hi,I am using STM32L151RCT6 MCU and creating the project in STM32cube IDE .i implemented DAC peripheral and kept 1.52 As input and did calculation like:float value = 1.52; // Dac outputuint32_t var; var = (value * 4096)/3.3 ; // From datasheet HA...
Dear Sir/madam,We are using Serial RTC chip(M41T93ZMY6F) in one of our application. In the datasheet,it is given as the RTC chip can be operated in the range of -40 deg C to +85 deg C.During Low temperature (-10 deg C), vacuum condition (5*10^-5 bar)...
Offset values shown in Table 84 are out of range according to Table 1.Also, "Address offset" of each COMP registers is different from the table.Section 10.1 says that the assignment of DMAMUX request multiplexer outputs to DMA controller channels is ...
Hi,I am using an STM32L010 and want to operate it in low power mode. The way the firmware works is I start the LPTIM2 with interrupt every 1 second and then go back to sleep once ISR is serviced. Right now the ISR just has a variable that acts a coun...
Hello,I enter stop mode using HAL_PWR_EnterSTOPMode and the processor come out of this function immediately and does not wait for any external interrupt. can someone help me on this?
I just started using CubeIde but using Cube examples gives a lot errors. Should I just copy all the .H and .C files (from where?) somewhere or is there a better way.I have 32H750 and 32F746 Discovery boards and my own boards.
