Posted on July 11, 2018 at 11:53My setup: STm32L053 nucleo and custum board with STm32L0. I am running a scan from nucleo borad for all possible I2C slave devices address in order to obtain the address of slave device ds1337.Both boards are connected on the same line. However, I can not receive the address unless custom boards is being disconnected from SDA and SCL lines.Using voltmeter I have noticed that:While both boards are connected SCL and SDA are in logic high.Custom board is not made by me, moreover I do not have access to it's code. The board is for production and I have to test it's DS1337 clock.Is it possible to read/write slave in this situation? How?Best regards,Ovidijus

Posted on June 25, 2018 at 17:44We are testing SBSFU on a 32L476_nucleo board, using the 2-image example project with IAR EWARM.We can reliably build and update the application in the way suggested.We would like the roll-back feature to work properly - we have been introducing deliberate bugs which cause application watch-dogs, and after 3 of these, SBSFU marks the downloaded application as BAD.  So far, so good.However, SBSFU refuses to roll back to the application in the other image slot because the reported version is the same as the new (buggy) application (in this case, 1). From the readme file in the application section of the project:3. Pressing 3 allows to call user defined services running in Secure Engine.As an example, SE_APP_GetActiveFwInfo service is called in order to display the firmware informationlocated in the protected area such as version and size.What is the correct way to define the application firmware version so that the secure engine can read it and

Posted on July 10, 2018 at 13:42Hi all,I am working on STM32F746G - DISCO. I have started working with STM32 just recently, sorry if this is a silly question. I need to use 1 timer to get PWM output from one of its channels, and generate time based interrupts from another channel. I have configured channel 1 for the PWM. The timer clock is 100MHz. ARR is set to (50000 - 1) and PSC is set to (2 - 1). Therefore I have achieved 1KHz PWM output of which duty cycle (CCR1) varies as needed. This part is perfectly fine. I have tried to configure channel 2 to generate time-based interrupts, which should vary in the range, let's say 1ms or less (for now). The output of the prescaler in this case is 50MHz, which means an interrupt should be generated every 50K clock ticks for 1ms delay. The timer is in the upcounting mode, the CNT counts up to ARR and then restarts from 0.  So the max value CCR2 can get is ARR (50000 - 1), and the maximum possible duration between two timer

Posted on July 05, 2018 at 10:42Greetings everyone,   I encountered a problem with CAN bus during individual work with STM microcontrollers. First of all I would like to give you some information on what I use.-I am using a microcontroller STM32f091CCTx-I use CubeMx software.   What I want to do is to view the CAN data from the CAN output of my card with PCAN Viewer.However, I can not get a result despite my long efforts and I open this post to discuss its reasons. First I want to share my CubeMx settings.I set the PB8 and PB9 outputs to Can Rx and Can Tx in the microcontroller schematic.I have chosen HSE crystal in the RCC as a clock because I have always seen it in similar cases.When I look at the clock settings, I learned that FCLK is used for the CAN bit rate setting. I set the clock rate to be 36Mhz according to the settings in the prescalar table because the bit rate I want to work is 500kbit/sec.To adjust the CAN settings, I made the Prescaler sett

Posted on June 19, 2018 at 18:13Looking to use ST NFC reader module for reading the tags and the reader must be able to send an unmodulated signal (carrier only at 13.56MHz). I also need to able to see the demodulated signal at one of the pins on the evaluation module. Is there any module that is available ? I am currently using EVAL-ST95HF but unfortunately not able to see the demodulated signal anywhere on the board. Any input on this is much appreciated.

Posted on June 25, 2018 at 00:29Hi. I am Reading a few APDU Commands from a card using the ST25R3911B and the STM32F401.I am using the X-CUBE-NFC5 software expansion.Before all my commands are completed, i get a 'ERR_NOMEM' error. I am clearing the (rfalIsoDepApduBufFormat)  txBuf and (rfalIsoDepApduBufFormat)  rxBuf every time before I run the rfalIsoDepStartApduTransceive(*par); command... Is there anything I should also clear to prevent the Out of Memory error? I have also tried to add delays between my APDU Commands to see if it would help.#nfc05 #x-cube-nfc5 #st25r3911b

Posted on July 09, 2018 at 21:26 I've been experimenting with writing to an external https://www.microchip.com/wwwproducts/en/93LC46B using SPI and I've had mixed success. The data does get shifted out but in an opposite manner. The EEPROM requires a start bit and then an opcode which is essentially a 2-bit code for read, write and erase. Essentially the start bit and the opcode are combined into one byte. I'm creating a 32-bit unsigned int and then bit-shifting the values into it. When I transmit these I see that the actual data is being seen first and then the SB+opcode and then the memory address. How do I reverse this to see the opcode first then the memory address and then the actual data. As seen in the image below, the data is BCDE, SB+opcode is 07 and the memory address is 3F. The correct sequence should be 07, 3F and then BCDE (I think!). Here is the code: uint8_t mem_addr = 0x3F; uint16_t data = 0xBCDE; uint32_t write_package = (ERASE << 24 | mem_addr <<

Posted on July 02, 2018 at 11:04 Hi I'm playing around with an ST25DV_Discovery_ANT_C6 and an ST25R3911B-DISCO development board to test the energy harvesting features. One result of my tests yields, that the output voltage V_EH is limitted to approx. 3.4V eventhough I can't find any explenation therefore in any application note or datasheet. R = 10kOhm In the datasheet of the ST25DVxxx is written, that the voltage V_EH is NOT regulated. If that's true, I'm not able to understand my measurements. Do you have any explenation for this behavior? Thanks and best regards Marco energy-harvesting st25dv64k st25r3911b-disco

Posted on July 06, 2018 at 16:23Hi, guys!Trying to connect the MCP4725 DAC to my STM32F103RB by following this tutorial:https://learn.adafruit.com/mcp4725-12-bit-dac-tutorial/ Sadly I'm getting no response. I've tried with a regular Arduino UNO, where everything works as it should. Also tried running a i2c scanner code, which gave no results. With the Arduino the correct address is 0x60.So do anybody know what I can do differently to get this working? Should the wiring be any different? What upload settings should I use?Best regards,Peter#i2c #f103 #arduino
