STM32f070xB, TIM16_CH1 input capture

I am using STM32f070xB controller. I want to use @TIM16_CH1 for input capture. GPIO_PIN: #PB8 Timer clock freq: 3MHz TIMER is getting interrupted continuously but after 120Hz, flow is not going into Capture compare callback. i.e, __HAL_TIM_GET_FLAG(htim, TIM_FLAG_CC1) is always RESET for frequency above 120Hz. Anyone can let me know,… (Show more Show less)

Yes, Compiler optimization is switched on. The same implementation with TIM14_ch1, Port A pin 4. TIM14 PB4 is able to capture interrupt till 2Khz (Maximum I have checked)

i am working on stm32f030c6t6 microcontroller.

Hi all, I am working on stm32f030c6t6 microcontroller. I want to use tim3_ch1 as pwm output. datasheet says that tim3_ch1 alternate function is available at two pins PA6 and PB4. I am not able to find that which pin default for this tim3_ch1 function and if want to remap another pin then how to do it. I have googled it. I found that in stm32f1… (Show more Show less)

Examples of sensored X-CUBE-SPN8 motor control with Hall sensor?

I found only more requests of the same in this forum and no answers. Using Hall sensors for motor control is most typical today. 6-step BLDC code example provided in X-CUBE-SPN8 is sensorless only. There are driver files in X-CUBE-SPN8 package specifically made for Hall sensored control (stm32f4xx_hal_tim_ex.c and stm32f4xx_hal_tim_ex.h) but no… (Show more Show less)

Giuseppe, please clarify: what do you mean by "The hall sensor code is supported instead for FOC control field-oriented control is sensorless... also what is "we have the solution already available for BLDC/PMSM motor" do you mean you have a solution/code example for Hall sensored motor control ? Where can we find it? Regards Vlad

STEVAL FCU0001V1

A few days ago I bought a board steval fcu001v1. This board comes with two defined programs. If I load any of these two programs the Open STM32 compiler compiles it and loads it. The problem is that when we give run the debugger starts to give error. Has someone from the forum used this board? If so, could you tell me if you could fly the drone… (Show more Show less)

Hi, nice to know you made progress and you were able to fly the drone! Here are some tips for you: - Can you post a photo of the frame you used: last year frame created a lot of vibrations and the FCU needs to struggle with it considering also the overall weight, we revised the drone frame and with the new one (Newest Toy drone frame with…

STM32F722IEK6 processor not counting properly

STM32F722IEK6 customer board, Eclipse Neon 3 Release (4.6.3) Hello All, I am having a weird problem that the processor/compiler seems not behaving normal. The for-loop delay counter for(m=0; m<1500; m++); running in the Canon_w() routine takes much longer than should be to finish whenever I run the delay loop below at the end of… (Show more Show less)

Brian Dang (to Brian Dang) 3 hours ago (Show more Show less)

OK, I think here is the reason why the for() loop counter is so unpredictable. It seems the compiler might optimize or ignore a dummy loop as the for(n=0; n< 500; n++); So I changed it to for(n=0; n<100; n++) Temp = SPI2.DR; // read SPI2 data register (assuming 100X read would have the same delay as wished. This forced the tool not to…

Ethernet Rx Interrupt Issue on STM32F4

I am currently using a STM32F407 board, with ethernet enabled in Interrupt mode, for the most part it works fine for UDP , I have the STM communicating to a another device via UDP using a switch, and in response to the STM request, the other device responds with some data over a switch. But when there is a lot of ARP'ing on the switch, due to… (Show more Show less)

STM32 SMBus Read Byte Error

I used ST supply STM32_AN4502_FW_V2.0.2 for SMBus.When test Read Byte command，0x19 can work，but 0x00 can not ACK right,TIMEOUT happen,Why?

STM32F072RBT as slave, GUI as master. PMBus communication. When use GUI Read Byte (CMD=0x00), After Add_Rd byte have about 25ms delay then STOP, but use GUI Read Byte(CMD=0x19), All OK.
