I'm developing a custom firmware for SP1ML but I miss important info regarding connections between the STM32L151RB and the SPIRIT chips.
Analysing the firmware loaded on the SP1ML, I understood that:PA5 ------> SPI1_SCK
PA6 ------> SPI1_MISO PA4 ------> SPI1_NSS PA7 ------> SPI1_MOSI PA1 ------> SPIRIT_SDNBut I fail to understand how the 4 different IRQ pins of the SPIRIT are connected to the STM32L151RB. I guess that an IRQ is connected to PC4 but I don't know the corresponding IRQ line on the SPIRIT.Regards,Dario #sp1ml-spirit1-stm32l151rb2016-03-07 02:09 PM
Hi Dario,
Have you been able to find out more about the connections between the STM32 and the SPIRIT1? I'm interested in your findings because like you I would like to run my own custom firmware inside the SP1ML module.Best regards,Patrick2016-03-11 03:30 AM
Ask an ST FAE about ''SP1ML detailed presentationV2.1.pdf''. As the section contaiming internal connections is labeled:
''SP1ML OpenPlatform  Optimized use cases'', I hope it is okay to give out the pin list. Please excuse eventual trancription errors. 1/TXRXLED=PA2 2/SHDN=PA0 3/GPIO0=PB15 4/GPIO1=PB14 5/MODE0=PB13 6/MODE1=PB12 9/SWDIO=PA13 10/SWCLK=PA14 11/BOOT0=BOOT0 12/RESET=NRST 13/TXD=PA9 14/RXD=PA10 15=PB6 16=PB7 SPIRIT/SDB= PA1 SPIRIT/CS = PA4 SPIRIT/SCLK=PA5 SPIRIT/MISO=PA6 SPIRIT/MOSI=PA7 SPIRIT/GPIO0=PC4 SPIRIT/GPIO2=PC5 SPIRIT/GPIO1=PB112016-03-12 12:02 PM
Thanks a lot Uwe!

Hi All,
Anyone know if PB6 and PB7 will work for I2C on custom firmware for the module? Would like to interface a humidity/temp sensor to this module. The STM32L151RB datasheet specifies these as I2C.
Cheers,
