Hi, I'm developing my digitally controlled SMPS using stm32g474 MCU, I found that the arguments of the functions "HAL_HRTIM_UpdateEnable" and "HAL_HRTIM_UpdateDisable" may be wrong, and the code of the two functions are copied as follow:In stm32g4xx...
Hi,Overall I liked the H5, lots of memory, lots of performance, 64-pin Ethernet, etc. I was only disappointed with the fact that it doesn't have HRTIM and only two AD converters. In addition to much more performance I expected analogue integration at...
I was getting strange results with the deadtime prescaler of the H7 hrtim and it appears that the H7 reference manual (RM0433 rev 7) is incorrect: The DTPRSC field of register HRTIM_DTxR, is supposed to get binary values from 011 to 111 (000 to 010...
I want to implement a complementary PWM pattern using the deadtime feature of the STM32G474. I found this example:Interestingly, the deadtime is not implemented with the on-chip deadtime feature, but with using multiple compares. Why is this?Is the s...
HiI am trying to implement a fault filter for the HRTIM on a stm32G474.I am using the LL libraries and the Reference manual.I find the table 234 in the reference manual completely unreadable and confusing. Could someone please explain how it is suppo...
I'm writting a very time-critical application for the STM32F334, where I have to control 4 power converters (mostly 3, one is time-shared another power converter). And recently I saw some ways to optimize code, like this://*********** 1360ns ********...
Hi Everyone,I am trying to run HRTIM Master unit with repetition interrupt and the repetition counter is 1. Now, when I am in interrupt I have to update compare and period registers and using LL to do so. But, within interrupt merely updating registe...
Hi Folks,Need a bit help in trying to figure out what's going on.I have been trying to port theen.stm32cubeg4_v1-2-0\STM32Cube_FW_G4_V1.2.0\Projects\B-G474E-DPOW1\Examples\FMACFMAC_Buck_VoltageMode_HW_AN5305to aNUCLEO-G474RE platform.I am trying to o...
Hi All,I am looking at the HRTIM CBC example here:https://github.com/STMicroelectronics/STM32CubeG4/blob/master/Projects/NUCLEO-G474RE/Examples_LL/HRTIM/HRTIM_CBC_Deadtime/Src/main.cThe questions are centred around EE5 and EE8 external inputs.I have ...
I compiled example from st cube. I found in clock configuration this parameters:RCC_OscInitStruct.PLL.PLLM = RCC_PLLM_DIV6; RCC_OscInitStruct.PLL.PLLN = 85;This give to sysclk 177Mhz and it exceeds max frequency... when I set parameters to:RCC_OscIni...
