i have a code in c of nxp mcu. in the code mcu nxp i configure pinout as: #define led PTBD_PTBD3 #define led_dir PTBDD_PTBDD3 i am using led in pin B3, next a use led_dir = 0;to define output,led=1 or led =0, to set or reset output, i wan...
I am using 2 Uart with interrupt function. I have enabled two interrupts at the same time. But I can access only one Uart at a time. Another Uart interrupt is no response.Kindly support for rectify this issue.
We have a B-CAMS-OMV attached to a Nucleo STM32H7 board, but we would like to work in monochrome mode, not RGB, the defaul mode for the example firmware.Does anyone know if the sensor (OV5640 from Omnivision) can work in monochrome mode? We tried mod...
I use this code to get the data ADC and transmit it but I can't see my data on Tera Term, I see my data in live Expression but not in Tera Term so most probably problem comes from Transmit part!! I would be happy if you take a look at the code that w...
Dear All, This is the first time that I make a question on a forum. I am an engineering student with any experience with this kind of boards/community, but I hope I can explain it as well as possible :) . Now I am working on making a serial conne...
What is the part number and/or where can I buy a cable from the ST-LINK to the B-U585-IOT02A board CN5?As a tangential question, why in the heck didn't ST just populate CN5 with a male 4-pin? (I'm a firmware guy, I don't solder, well, perhaps until n...
Our design and firmware used to work with former batch but a current lot of STM32F427 does not have a proper readout of the flash size and does not switch from bank A<->B.The STlink reads the following on a working chip:STM32 ST-LINK CLI v3.2.0.0STM3...
I've got a few of the Aliexpress Chinese STM32F407VET6 development boards that arrived recently. I became suspicious when the content of 0x1FFF7A22 is reported as 0xffff, when it should be the flash size in KB. The MCU chip itself reads:STM32f407VE...
Hi there,I just wondered if any of you would have an idea about my current problem, or faced similar challenges:For a new project I would need about 20 configurable EXTI lines, which exceeds the number of any STM32 MCU as far as we know. How could we...
