I am trying to do a general HAL_I2C_Master_Transmit. Everything is fine until I come here: /* Write data to TXDR */ hi2c->Instance->TXDR = *hi2c->pBuffPtr;When I pass this line, the ARLO bit is set in I2C->ISR. My pBuffPtr is correct. It's litera...
I am working through a workshop tutorial on how to configure and use GPDMA transfers via the linked list functionality provided in STM32CUBEMX. When setting the linked list runtime configuration a Source Address, Destination Address and Data size are...
Hi ,I am working on STM32L0 series controller with VD6283TX ALS on I2C interface.Though code is available for the sensor, my requirement is to write own code that will control the sensor. Sometimes it reads the RAW data from sensor and sometimes it ...
I have initialized I2C on BlueNRG-248 as a master, and it is able to successfully transmit address and data to the slave, but is unable to receive data and acknowledgement from it. I monitored the lines on an oscilloscope, and confirmed that the slav...
Hi All,Some of the grander Evaluation/Discovery boards use an STM32L152 as a slave Multi Function eXpander with an I2C interface. It's pre-programmed with firmware that provides access to some of the peripherals on the board.As it happens, I'm about ...
Relating to STUSB4700 / 4710 datasheet I suggest the device address is the same as for 4700 with all adr pins set to 0.But no description in 4761 datasheet for I2C interface or register map.
Hi,attached is the code for I2C where we are trying to read from the sensor connected using I2C...I2C_mem_write or I2C_Master Transmit...nothing is sent by the sensor.any change in the coonfiguration ..kindly let us know.attached the IOC file also......
Hello,I am looking into designing a board (sink only) which uses said IC to allow me to use the 15W from the source/PD-compliant source.From what I understand, the I2C interface attached to a master is used (in addition to other functions) to communi...
I am using vcsel driver that i thought uses i2c but it uses two wire serial interface with 11 bit shift registor 3 for address less than the usual 7 bit address and I heard I could bitbang but I couldn't find it possible anywhere please look at datas...
For some reason I need to rewrite I2C functions from HAL to LL. As I aim to achieve good power consumption results, I decided to use DMA and IT in order to save as much resources as I can. There is all ok with writing data (HAL1 and LL1 pictures) but...
