Solved

HI everybody,i am using STM32G0B1 and in an older project i used successful ADC multichannel DMA conversion of 8 channel. I started a multichannel ADC conversion of 8 channel and a ADC callbacksets the finished bit and later on i read the result for 8 channel from DMA buffer and start a new 8-chan conversion again. It works well.For a new project i want to keep this method for 10 channel but unfortunately i can only convert 8 channelone after another, the Number Of Conversion in ADC Paramter Setting in MXCube is maximum 8,I guess, due to the ADC channel selection register, reserved only for max. 8 channel.Now my question, how can i setup a DMA multichannel ADC conversion for 10 channelwithout reprogramming Channel and Rank before each conversion ?Possibly by an injected conversion of the 2 upper channel - if yes, pls with a hint for setting it right in CubeMXand possible HAL code.Thanks in advance,Kai

How in the world is this happening now? Just made some changes there. Renamed and changed the values.The first line has "missing whitespace after the macro name" Aprilfools day is still not here yet!  

I am a new user of H563ZI, and I have read the datasheet. I wonder if all pins that can be viewed in cubeIDE can be used as a GPIO pin?For example, as mentioned in the datasheet, PB2 is used as QSPI_CK when solder bridge configurations are not changed. Can I use it as GPIO_OUTPUT pin by just configuring it in cubeIDE without modifying the solder bridges?If not, then the actual numbers of pins that can be used is just as many as the Arduino pins? I am quite confused.

 Hi,I have debugged my application and came to know, there is problem at SystemClock_Config(); yet I do not know what the issue, please see clock configuration in below as well.I have also commented out SystemClock_Config() and debugged again, this time error_handler() is called aat MX_RTC_Init() function. I suspect that, there is something wrong with my clock configuration, I just can not see what that is.When I commented out MX_RTC_Init() function, the application runs flawlessly. Thus, after debugging I made it sure that the problem is with initialization of both system clock and RTC.I hope I have made the topic clear, else please let me know for further information. Thanks for the support, much appreciated.I have though that LSE (32.78kHz) is already inside the board. So, if I am mistaken then it might be the root cause.Could you please help me resolve ? /* USER CODE BEGIN Header */ /** ******************************************************************************

I inherited a board that has a SM06B-XSRS-ETB JST connector for the SWD port.  I believe they were using an ST-Link programmer. Does the ST Link programmer come with an adapter cable that has the male side of the connector?  Or is there a cable available? I would like to think they chose a standard connector for the design but I am not having luck finding one.

In my  project, i will  to communicate with a cluster of cars that support the CAN FD protocol, operating at a baud rate of 500 kbit/s with a data payload of 12 bytes.  my plan to interface this communication with a NucleoH745zi-Q board, which supports CAN FD. However, i  currently have  an MCP2551 transceiver designed for classical CAN .can'i do this communication with NucleoH745zi-Q board and MCP2551 transceiver !!! thank u    

Hi, I am working on a firmware for STM32F103C8T6 with 128KB of flash. When I create a new project in the STMCubeIDE by default it sets the flash size to 64KB. I have changed the flash size in the linker file to 128KB. Is it the only change required or some more required? Thank you.

Hello, I need to be able to generate a small DC voltage from an AC voltage.  The App Note 4260 looked absolutely perfect - exactly what I needed - 12V 150mA buck converter.  Simple. no flyback transformers, etc.  But I was a bit confused as to the GND connection on the IC.  It looks like it is connecting to the V-Out instead, with a diode to gnd.So i went into the edesign suite and used the exact same parameters.  the design it shows before you hit "Start design" also shows the diode to gnd on the GND pin, but it also shows another ground symbol.  Can you clarify the two different grounds?The other thing I noticed - it shows a bridge rectifier on the AC input before you tap "start design", but the app note and design you see after you tap "start design" just show the simple single diode rectifier. Can you clarify if I need to add a bridge rectifier on the front? Do I also need the other diode then?

HiIn our design, we incorporated the IMS T225-F20E component. This part necessitates a clock with a frequency of 5 MHz. According to note 3 in the attached image, crystal oscillators with a 200 ppm (parts per million) tolerance can be employed. However, this information pertains to scenarios where two devices are connected together by a link. Now, the question is: What is the allowable tolerance for the clock oscillator if only one device is used?”I am currently working on crystal aging analysis. It would be beneficial if you could furnish the allowable tolerance data for the device.   Thanks in advance 

Dear all, the first of all thanks for let me leave a message in this post.We have a schematic circuit, with the LM324 it works but with the LM358 doesn´t work. It gives the correct voltage in both chips in the output, I connect a relay solid state from Carlos Gavazi and with the LM324 works and with the LM358 doesn`t works. the differents inside the chips are ( picture attach).I check the mA output and all is correct. the consume of solid state relay is only 10mASomebody have this error? Which difference the are between the LM324 and LM358? could somebody give me a refference form a LM324 in two cannels? thanks in advanced Thanks in advanced. 

Good day @ ST.  How can one get in contact with the right person at ST, when we wish to know a little more about SOI ?Sincerely  Klavs Rommedahl.

With revision Z of the STM32H563VIT6, which looks to be an older revision of the MCU, we get a HardFault issue in the UCPD library. We noticed the issue with revision Z, but revision X is working as expected (see errata in attachments)! When connecting a device through USB-C, the MCU goes in a HardFault when setting Rp resistors to SinkTxNG.In the STM UCPD library, I see that there is some added code to manage older revision of the component, and the line with the red arrow creates the HardFault.It seems that the MCU is not able to access "pUCPD_TRIM_1A5_CC1" value in non-volatile memory at address 0x08FFF844, even though there is a value at this address if I manually look for it in the flash.What could create this HardFault?Is there something we can do to fix this HardFault or should we discard all revisions other than the X?

Hi Everyone,I use SDMMC on my STM32H7 to write data on SD Card. I have several question :- for now I can't reach better rates than 12Mo/s writing, using 32Ko buffers and with the stm32 doing only that. Is that normal? I think I should reach the 25Mo/s announced by the High Speed Sd Card mode.- when the stm32 is running normally, I can't reach better rates than 7.5Mo/s in High Speed SD Card mode. Once again, is it a normal rate or could I do better ?- Those rates are in high speed mode in 3.3V. Should I consider to use a level shifter to write in 1.8V with SDR50 or SDR104 ? Thank you very much !

HiI am facing an odd problem with ADC in conjunction with DMA on STM32L151V8T-A. I can see that it measures all three channels. However, the result of each channel is stored in the first element of my results array (Result[3]). Every time that the callback function is called the results of one out of three channels is stored in Result[0] element. It is as if the memory address is not increasing.Can somebody help?

Hi, I'm working on a board that has a USB PD input and a USB PD output.The board initialises via a generic PD 100W charger connected to the USB-C input, negotiating power for 20V / 5A via the STUSB4500. After this, I'm trying to source the voltage to a secondary board, connecting the STUSB4500 output directly to a PD Source chip, which will again connect to an STUSB4500 in this secondary board. I tried to do this with the STUSB4761 PD Source chip, but the chip is not negotiating or outputting any voltage. I realised the chip has a feedback pin and probably only works with AC/DC supplies. Is there anything I can do to make this work? In other words, this is the scheme I tried:External power supply (100W) > USB-C CABLE > PCB#1: STUSB4500 + STUSB4761 > USB-C CABLE > PCB#2: STUSB4500 and so on... (this will repeat on a daisy-chain for at least 6 PCBs).One more question, would it be better to have a STUSB4700 for the source in this situation? Can I link the STUSB4500 to an STUSB

Hello,Iam developing RS485 on STM32H753. I use STM32Cube (*.IOC file) for USART configuration (USART with Hardware Flow Control) and everything works perfectly. But last send char by processor is also received in RX buffer. Does anyone know how to prevent this behavior? Thank you for your response.
