Does the STM32L100RC have a temperature sensor?RM0038 refers to the temperature sensor in the STM32L1 line of processors. However, the STM32L100RC datasheet only mentions "tempsensor" in table 4 and nothing else anywhere. CubeIDE will allow the temperature sensor ADC channel to be selected but apparently no code is generated. There's a macro in stm32l1xx_ll_adc.h , __LL_ADC_CALC_TEMPERATURE_TYP_PARAMS(), for converting the value to celsius but it requires parameters from the datasheet that don't exist: avg_slope and V110. These parameters exist in other datasheets, however. The comment near the macro sure seems to imply that the processor has the sensor, just not the cal constants: /* Note: On device STM32L100, calibration parameters TS_CAL1 and TS_CAL2 are not available. */ /* Therefore, helper macro __LL_ADC_CALC_TEMPERATURE() is not available.*/ /* Use helper macro @ref __LL_ADC_CALC_TEMPERATURE_TYP_PARAMS(). */ /* * __TEMPSENSOR_TYP_AVGSLOPE__ Device datasheet data: Tem

There is "96-bit unique ID" in the datasheet (DS13514 Rev 2 ). The feature is also listed on product page . But there is no mention of unique ID in the reference manual (RM0454 Rev 5). Does the MCU have unique ID and how it can be accessed?

Hi, We want to incorporate the STLink firmware binary provided by STMicroelectronics here onto our custom STM32 board with stlink circuit. However, we would like to seek clarification on whether this usage would allow us to sell our custom board commercially.We kindly request your assistance in understanding the implications of the license agreement when binary is distributed via inside the chip and any potential limitations or permissions for commercial usage of STLink firmware on a custom board. Thanks

I have some re-used and portable code that uses <assert.h> and assert().Is there a way I can easily map assert() to the assert_param() used by CubeMX?Seems so simple but it is giving me a hard time, and I don't see anything available online about this.

This is weird.  Also it was working at one point and stopped working, can't track down the code change that broke this. So, I use HAL_UART_Receive_DMA() to start a DMA RX.  I can use _HAL_DMA_GET_COUNTER() to check how many characters have been received and I am receiving characters, but the contents of the buffer I passed to HAL_UART_Receive_DMA() is not changing.  Why would the DMA counter increase but not the memory buffer contents?  I checked the hdmarx handle in the UART handle, the Instance pointer in the hdamarx handle, and the MOAR and PAR pointers in the DMA peripheral - everything looks correct. What more can I do to try to diagnose this problem? Normal DMA (not circular), Peripheral to Memory.  Interrupt should be enabled but I don't think I need it with checking the buffer contents as it's received. I got the idea to poll DMA contents while receiving from this blog post:https://blog.stratifylabs.dev/device/2021-12-30-UA

Hello community, I'm working on a STM32F107VCT6 where I have practically (by means of very basic filtering) shorted on the PCB VDD/VDDA/VREF+/VBAT and VSS/VSSA/VREF-.   I've runned out of pins so I was wondering if there were a way to measure the power supply (without using external ADC channels) which supplies the MCU (VDD) for the purpose of evaluating the upstream power supply conversion (done by a DCDC).   An interesting application here on the forum based on STM32L010F4 using VREFINT_CAL solution could have been perfect if only STM32F107 had this register (which actually don't).   As a desperate attempt I was doing Vsupply=3.3V*Vrefint/Vmeas. Where Vrefint=1.20V from datasheet, Vmeas is Vrefint measured by means of ADC1 "Vrefint Channel". But it seems stupid to me because falls in a circular reference thus the Vsupply will always be calculated as 3.30V... Or maybe not?   Any smarter solutions?   Thanks in advance.

I have over 25 years in embedded design but I am new to ST and ARM cores. I am looking at the STM32 MCU's to replace a 32bit MCU I am already using, the only feature I don't need is the graphics system as we have our own GUI hardware and firmware. I need at least 2M of code, preferably able to move up to 4M when needed without respinning the boards. What dev board and core would you more experienced developers recommend for me to get started with? No special needs except for USB, CAN, UART, SPI, QSPI, and I2C ports to connect all my standard peripheral devices. TIA!Larry Affelt

Hello,For a few months now I have been having issues with writing data to flash memory on the STM32H743ZIT6. Most of the time, everything works great and I am able to read the data from flash successfully, but every now and again, the flash memory gets corrupted somehow and ECC codes are thrown (both single and double), which causes my device to have a bus fault.I am running the flash peripheral / AXI bus at 240Mhz and I have the flash wait states set to 4 WS (5 Flash clock cycles). I have followed all the guidelines related to the HW design and have the correct core capacitance on the VCAP pins. I write 256 bits of data to the flash memory approximately every 10 seconds to save the state of my device (of course I increment the write address after each write so that I'm not writing to the same position every time). When the sector is filled, it is then erased and then I start writing to the start of the sector. I also set the BOR bits to the highest voltage setting to try and prevent b

I use spi1 as the slave to receive data, and if the speed of the spi master is set above 11M, the data received will be misaligned.I would like to know what is the maximum speed supported by the SPI peripheral on the stm32h503rbt6u chip in the slave mode?

I am not able to receive the full string in the RDR resgister. eg. If I am transmitting "hello" I am receiving only "h". How to get a full string? Can anyone please help? uint8_t Temp;  while( !( USART2->ISR & USART_ISR_RXNE ) ) {   Temp = USART2->RDR;  HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET);   };

Hello,i have few problems with the new version of Touchgfx 4.221. When using Dynamic Graph every time the code is generated the Base class is broken. This effect was also observed in previous versions. If the Line / Array sequence is changed and restored again and the code is generated again then all is well. 2. On Touchgfx 4.22 I have problem with vertical text version 4.21.4version 4.22Greetings Boyan Panchev

Hi,I am having issue to find a work around this parameter.I do not specifically set any over voltage threshold but it seems to be present there already, so i am guessing that's something hard wired by ST. Is there a way, other than changing manually to change this value?Thanks in advance.

Hello,I am working on integrating SBSFU with the STM32F4 controller. The target controller is F429.I am trying to build an example project.

Hello,for determining the Stack-Utilization I fill it with 0xDADBEEF. If you have recommendations and other ideas, I’d like to know and looking forward to learn from others, how they approach the issues “Stacksize” and “Stackutilization”.Code for the Startup-File: Reset_Handler: /* BEGIN : Seppels StackInit*/ ldr r0, = _End_Min_Stack_Size ldr r1, = _estack ldr r2, =0xDEADBEEF Fill: str r2, [R0], #4 cmp r0, r1 bne Fill /* END : Seppels Stack Init */ Modification of the Linker-Script: /* Highest address of the user mode stack */ _estack = ORIGIN(RAM) + LENGTH(RAM); /* end of "RAM" Ram type memory */ _Min_Heap_Size = 0x2000 ; /* required amount of heap */ _Min_Stack_Size = 0x2000 ; /* required amount of stack */ _End_Min_Stack_Size = _estack - _Min_Stack_Size ; /* Calculate the lower Address for init with the famoes "EB" */ Top of the Stack:Thanks a lot.Best Regards, Seppeltronics

I'm trying to do a program like a baby crying and i'm looking for the code of babycrying program. I need to do a program that detects unwanted noises in cars, so i think that maybe is similar than the babycrying app.I thought it was possible using the expert mode, but now I think it is not possible with it. If someone could help me pls, maybe with some information or the babycrying code I would appreciate it.

Hi, I am having a trouble using MCWorkbench 6.1.1When downloading a project generated from MCWorkbench demo to my B-G431B-ESC1, this happens(the rotor moves for some angle per each second while making a wierd noise. It temporarily stops when I push the start/stop button in the ESC(ESC generates low beep sound))ST-Link FW : V2J41M27Demo : Electronic Speed Control on B-G431B-ESC1 kitI did not modify any .ioc file(cubeMX) or  .cproject Any advice would be helpful.

When I use vl53l5cx_get_target_order, it returns 2.I assume there are only two values (1 & 2). Does 2 = CLOSEST or Strongest?Thanks.Giri

Hi all,I'm new to the STM32 world and ST motor control tools, so I might be missing something obvious.I have the B-G431B-ESC1 development board connected to a BLDC motor.I generated the code for FOC with the MC-WB 6.1.2 and STCubeMX 6.8.1. Compiled with STM32CubeIDE 1.12.1. Connecting to the board and upload worked well. I can connect with the Motor Pilot 1.1.12 to the board.The board generates a repeated beeping noise with 1 Hz frequency. Is that normal?When I try to accelerate the motor via the GUI, the board initially responds but aborts. It sounds like the "beeping" generator is still active. To test, I set the duration of the first phase to 10 seconds in the Rev-UP dialog and reduce the torque. This generates the current profile shown below. The current follows the reference value most of the time, but is periodically disturbed. This disturbance follows the rythm of the beeping. If I set the reference current higher (to generate enough torque to turn the motor), the controller tri

When i refer the source code of the B-G431B-ESC1 board, i do not see the code check for series resistance, inductance of the motor. Is the source code independent of the series and inductance of the motor? For example/***************** MOTOR ELECTRICAL PARAMETERS ******************************/#define RS           0.35 /* Stator resistance , ohm*/#define LS           0.0006 /* Stator inductance, HBut i do not see these parameters used anywhere in the program. Is my understanding correct?

but i am not able to read the data in slave module, how to connect this with the host and camera module processor and read the data, is there any settings have to be mentioned.? if any one information about this it will be helpful.

I am encountering a strange problem on the VL53L5CX sensor. Here is the rundown of my setup:3 sensorseach gets initialised and new i2c address is set so they can run simultaneouslyturn all sensors on and wait for external inputThe external input is simply an interrupt from a pin (yes I do block interrupt calls while this process is running so theres no overlap). Upon this interrupt being fired the following occurs:Each sensor sent the start_ranging() commandeach sensor takes 10 measurements (this is done by looping over each sensor and calling the check_ranging_data() command and then get_ranging_data() )after 10 measurements each sensor is sent the stop_ranging() commandThis is where the problem occurs, the first 2 sensors have no problem stopping, then the final sensor seems to timeout during this function call and returns an error 49 (decimal). What would cause the stop_ranging() command to fail? How does it even fail? How is it more complicated than to just stop all ranging process

 Hi, I'm using the UART on a STM32G071 MCU. To read data  get  an interrupt when the FIFO reach the FIFO reaches the  threshold of 1/2.Inside the interrupt routine I check if there are uart errors.If I get some errors I want to discard data received. Before quit from the interrupt routine I want to empty the FIFO reading all  the bytes received. I didn't find any bit on UART registers that indicate that FIFO si completely empty. Can you help me? Is there any other way to get the FIFO empty?

Is there a Motor profiler API or any other tool that I can use to retrieve the error status from the ST Motor pilot programmatically? I'm interested in obtaining informations about the following errors:If it's not available, I would appreciate any alternative recommendations or approaches to achieve this functionality within a code-based context.
