Re: WEACT STM32F411CE SUPPORT AND I2c

and now for the I2c,,The front page from st has an image for 5 x i2c devices, I need 3 separate devices (same i2c address) en.bd_stm32f411xe_512k.jpg from the board layout of the weact I can only make out some vauge i2c pins.. https://github.com/WeActTC/MiniF4-STM32F4x1/blob/master/images/STM32F4x1_...

Re: WEACT STM32F411CE SUPPORT AND I2c

Using for example a cp2102 or other uart adapters? Or via the USB c port? I will try now the Uart adapter. I also ha ve a stlink V3 can not find any documentation to use it on this board

WEACT STM32F411CE SUPPORT AND I2c

Coming from the blue pill and needing some more i2c I got some of the weact stm32f11 boards. Just wondering if there is any sensible method to get this compiling at all under the stm32duino? Any tips from those who have tried or suggestions on board settings/ bootloaders to use? https://github.com/W...

Re: software i2c?

these particular i2c devices dont have a changeable address..its the as5600.

Re: software i2c?

1 need 3 i2C devices in this blue pill while at the same time 12 hardware PWMs pins. Either core wouldnt bother me if I knew it was going to work...either that or porting the softwire to the other core.... :idea: ?

software i2c?

Ive run out of pins to use i2c on my blue pill and would love to try software i2c. I cant see any in the example but perhaps someone else has some more info?

Thanks Ray, I had not installed them..still getting used to using the stm32 but now loving that hardware PWM:)

Re: how many SPI or alternative devices with STM32F103C8T6

Hey thats very helpful information thank you. I think I will get my hands on some of those devices you mentioned for testing things out. I guess I should also clarify that each of the things I am building use 3 magnetic sensors per robot..perhaps thats more feasible to think about 3 on the blue pill...

how many SPI or alternative devices with STM32F103C8T6

I prototyping a project using multiple magnetic sensors that either use SPI, SSI, I2c..encoded PWM or quadrature output..that's a mouthful. Trade offs with this project are simply cost, I need a lot of sensors (hundreds) The cheaper of the sensors such as the as5600 or as5200l have i2c but they are ...
