TLC5973 driver in Golang for Raspberry Pi

This is a simple example on how to interface with a TLC5973 IC to dim LEDs in Raspberry Pi.

It uses SPI to generate a pulse train with precise timing.

In Raspberry Pi, the SPI may have some inter-byte delay, which makes this useless. More here: https://www.raspberrypi.org/forums/viewtopic.php?t=211152

I'm using go-rpio to manage the SPI device.

The idea to use SPI came from this repo: https://github.com/mik4el/cc1350-swim-thermo/blob/b2fdb54a940e18911959a5e1778ca7fc06915a11/software/tlc5973_spimaster_CC1350_SWIMTHERMO_tirtos_ccs/spimaster.c

Pega o saldo da conta SIP Trunk da DirectCall

Para contas tipo SIP Trunk da DirectCall, não existe API(Existe mas é paga) para pegar o saldo atual da conta.

Criei este script para facilitar o acompanhamento do saldo, sem precisar entrar na interface web.

O script retorna 0 caso seja invocado sem argumentos ou caso o argumento seja maior que o saldo atual. Exemplo:

$ ./saldo.sh
312,64
$ echo $?
