I am using etpu_FPM to get a freq for 4 channel
with AN2859SW, I can use a function < fs_etpu_fpm_get_freq >
but i came to get a wrong freq at first time. when There is no input.
For example, I want to put freq values into variable "FREQ "
although I initialize variable "FREQ " at first time, but then. variable "FREQ " is full of unusual value (When No input)
but if input is nomal, variable "FREQ " come to be full of nomal values
I think it is problem about initialization of ram
Here is My code.. Thank you. <fs_etpu_fpm_get_freq(), fs_etpu_init() > are same as AN2859SW
------------------------------------------------------------------------------------------------------------------------------------------------------------------------
uint16_t FREQ;
fs_etpu_init( my_etpu_config, (uint32_t *)etpu_code, sizeof(etpu_code),
(uint32_t *)etpu_globals, sizeof(etpu_globals));
| err_code = fs_etpu_fpm_init (16, | /* engine: A; channel: 16 */ |
| FS_ETPU_PRIORITY_MIDDLE, | /* priority: Middle */ |
| FS_ETPU_FPM_CONTINUOUS, | /* mode: FS_ETPU_FPM_SINGLE_SHOT */ |
| FS_ETPU_FPM_RISING_EDGE, | /* edge: FS_ETPU_FPM_RISING_EDGE */ |
| FS_ETPU_TCR1, | /* timebase: TCR1 */ |
| 1200000); | /* window_size: 1200000 */ |
if (err_code != 0)
FREQ = fs_etpu_fpm_get_freq(16, 150000000);
