The Peltier Click is a Click board™ which utilizes the SPV1050, an ultralow power energy harvester and battery charger from STMicroelectronics. The Peltier Click can charge lithium battery using thermoelectric energy harvesting device (TEG).
We provide a library for the Peltier Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Peltier Click driver.
Config Object Initialization function.
void peltier_cfg_setup ( peltier_cfg_t *cfg );
Initialization function.
PELTIER_RETVAL peltier_init ( peltier_t ctx, peltier_cfg_t cfg );
Enables LDO2 function.
void peltier_enable_ldo2 ( peltier_t *ctx );
Disables LDO2 function.
void peltier_disable_ldo2 ( peltier_t *ctx );
Check ongoing battery charge flag pin function.
uint8_t peltier_battery_charge ( peltier_t *ctx );
This application is ultralow power energy harvester and battery charger.
The demo application is composed of two sections :
Initializes GPIO driver, disables both 1.8V and 3.3V outputs and starts write log.
void application_init ( void )
{
log_cfg_t log_cfg;
peltier_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info(&logger, "---- Application Init ----");
// Click initialization.
peltier_cfg_setup( &cfg );
PELTIER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
peltier_init( &peltier, &cfg );
}
This example demonstrates the use of Peltier Click board by first enableing 1.8V output, second by enableing 3.3V output, then enabling both outputs and finally disabling both outputs in 5 seconds intervals.
void application_task ( void )
{
log_printf( &logger, " 1.8V output \r\n" );
log_printf( &logger, "------------------\r\n" );
peltier_enable_ldo1( &peltier );
peltier_disable_ldo2( &peltier );

log_printf( &logger, "------------------\r\n" );

peltier_enable_ldo2( &peltier );
Delay_ms ( 1000 );
Delay_ms ( 1000 );

log_printf( &logger, " Both outputs \r\n" );
log_printf( &logger, "------------------\r\n" );

Delay_ms ( 1000 );

Delay_ms ( 1000 );
log_printf( &logger, " Disable outputs \r\n" );
log_printf( &logger, "------------------\r\n" );
peltier_disable_ldo1( &peltier );
peltier_disable_ldo2( &peltier );

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations
Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
