Detailed Description

Main driver class for the ADS7952 12-channel, 12-bit SAR ADC.

Copyright

Copyright (c) 2024-2025 HardFOC. All rights reserved.

Hardware-agnostic C++20 driver for the Texas Instruments ADS7952 multichannel SAR ADC using CRTP for zero-overhead SPI abstraction.

Key Features

• 12 analog input channels, 12-bit resolution, up to 1 MSPS
• Manual, Auto-1, and Auto-2 channel sequencing modes
• Configurable input range (Vref or 2*Vref, clamped to VA)
• GPIO programming (4 pins with alarm routing)
• Per-channel alarm threshold programming (high/low)
• Power-down control
• Direct imperative SPI sequences (no state machine overhead)
• Proper first-frame discard after power-up per datasheet spec

Basic Usage

class MySpi : public ads7952::SpiInterface<MySpi> {
public:
  bool transfer(const uint8_t* tx, uint8_t* rx, size_t len) { ... }  // false = bus error
};
 
MySpi spi;
ads7952::ADS7952<MySpi> adc(spi, 2.5f, 5.0f);
adc.EnsureInitialized();  // Idempotent — safe to call repeatedly
 
auto result = adc.ReadChannel(3);
if (result.ok()) printf("CH3: %.3f V\n", result.voltage);
 
auto all = adc.ReadAllChannels();
for (uint8_t ch = 0; ch < 12; ch++)
  if (all.hasChannel(ch)) printf("CH%u: %u\n", ch, all.count[ch]);
