Hello
I implement R_CTSU_Diagnosis() for a project that need VDE aproval https://renesas.github.io/fsp/group___c_t_s_u.html#ga45103e8db4a16dfabf3a516ab2da9f26 in RA2E1 microcontroller
The function works well, when I power microcontroller at 5V, but if I decrease microcontroller voltage to 4.90V function reports FSP_ERR_CTSU_DIAG_OUTPUT_VOLTAGE. Error code 6009.
Error occurs ( I think because made a internal reference measurement with assumption that power supply is 5.00V and check values with limits defined :
#define CTSU_DIAG_TSCAP_RANGE_LOW (1050) #define CTSU_DIAG_TSCAP_RANGE_HIGH (1419)
What is the expected value of this measurement at Vcc 5V? and we can revise defines in order allow wokring with a microcontroller Vcc range between 4,5 and 5V?
Hello,
Let me check this and I will get back to you.
The #define values assume an operating voltage of 5V.
We are checking on how these values should be dynamically scaled to reflect the operating voltage of 4.5 to 5V.
Regards
Some feedback?
The diagnostic driver expects a fixed voltage.
I am pending foir some internal information on how to accommodate the variable voltage of 4.5 - 5V
Some feedback? :)
We have some feedback and workaround which will be provided to you by your local FAE.
