I have read the document RM0433 and AN4235, but the calculation is still a puzzle. For example, if my I2C frequency = 1MHz, I2C clock source frequency = 170MHz, AF=on, DF=off, rise time = 8...
...onfigured the GPIOs and the modes but I am stuck at the "I2C_TIMINGR". I went through the I2C_TIMINGR register configuration examples on Pg. 1982 - 1984 of the reference sheet for the H753 but I w...
I try to write the driver for I2C and I open the reference I face a problem in setting values for SCLDEL SDADEL SCLH SCLL and I don't know how to set theses values. I kept searching and I saw there i...
Hi, Can anyone point me in the direction of some more information about the custom timing under the I2C parameter settings? Are we modifying a specific register? or something else? Do each of the 8...
Hi All, I trying to interface MAX6651 Device using I2C module using STM32F410C8U6 MCU. Device address is 0x36 But when i'm using HAL_FMPI2C_IsDeviceReady(&hfmpi2c1, 0x36 , 2, 100); thi...
HI Team, We are using the STM32WB controller for our project, in that we are using the I2C1 for to communicate with Eeprom Module. Can anyone explain how to configure/Calculate the Exact Timing Reg...
I am looking for a way to change the HAL I2C lib clock speed during runtime to either 100k or 400k or 1M. I tried the following..... hi2c1.Init.ClockSpeed = 100000; However when co...
