Hi,
I have problem with LTC7106 and STM32G431CBT6.
LTC7106 use PMBUS. I never used SMBUS or PMBUS before.
I tried to use normal SMBUS implementation and:
- I can find device (it find 0xC, 0x2A, 0x5A, 0x5B devices. First one is strange but maybe I don’t know something) - the device should have 0x2A address - so I assume that it work properly.
- I can’t force it to send or receive any data from the device.
I tried to do everything as described in: SMBUS/SMBUS_TSENSOR/readme.txt in terms of configuration – but I have no idea what cause the problem.
So I have a question – does PMBUS device should be accessible via standard implementation od SMBUS in STM32? I mean should it read and write registers without any problems?
To solve the problem I tried to use X-CUBE-SMBUS – I tried to do everything like in: https://community.st.com/t5/stm32-mcus-products/this-is-an-issue-related-to-the-initialization-of-the-x-cube/m-p/751304 and in AN4502
But it hang in STACK_SMBUS_Init -> SMBUS_Enable_IRQ -> __HAL_SMBUS_ENABLE_IT(hsmbus, tmpisr);
Since there is almost nothing usable information in internet I have a second question. Do you know what can cause this problem?
