Description
Evaluation Board for iC-TW29 with MCU (for BiSS)
This evaluation can be used with the onboard preconfigured STM32 MCU allowing BiSS passthrough communication with the iC-TW29. The STM32 MCU can also be disabled allowing configuration via the standard TW29_1D programmer and iC-TW29 PC GUI.
When the MCU is enabled (JP8 removed), the MCU
configures the iC-TW29 in BiSS passthrough mode
(BISS_CFG2.passmode = 2). In this mode, all accesses to BiSS slave registers are passed through
to the host processor (U7; STM32L431KBU6). The
host processor responds as required and passes the
requested data back to the iC-TW29 through the SPI
interface.
To use the TW29_1D programmer with the TW29_4D
eval board, first install JP8 on the TW29_4D to disable
the on-board MCU. Then connect P5 on the TW29_1D
Programmer to J4 on the TW29_4D using the supplied
10-pin ribbon cable jumper as shown in Figure 9 of the evaluation board manual.
